Most often Medicare Advantage gives you better benefits than your original Medicare.
A Medicare Advantage Plan (known as Medicare Part C) is a health plan through a private insurance company that contracts with Medicare to provide you with all of your Part A and Part B benefits.
Medicare Advantage plans include Health Maintenance Organizations, Preferred Provider Organizations, Private Fee-for-Service Plans, Special Needs Plans, and Medicare Medical Savings Account Plans.
If you’re enrolled in a Medicare Advantage Plan, Medicare services are covered through the plan and aren’t paid for under Original Medicare.
Most Medicare Advantage Plans offer prescription drug coverage. If not, you you can purchase an additional Part D plan.
